I would like to compile via sbt to WAR instead of JAR file and I followed this guide.
I have changed the build.sbt to:
libraryDependencies ++= Seq(
"org.http4s" %% "http4s-jetty" % Http4sVersion,
"org.http4s" %% "http4s-jetty-client" % Http4sVersion,
"org.http4s" %% "http4s-circe" % Http4sVersion,
"org.http4s" %% "http4s-dsl" % Http4sVersion,
"io.circe" %% "circe-generic" % CirceVersion,
"org.specs2" %% "specs2-core" % Specs2Version % "test",
"ch.qos.logback" % "logback-classic" % LogbackVersion
),
addCompilerPlugin("org.typelevel" %% "kind-projector" % "0.10.3"),
addCompilerPlugin("com.olegpy" %% "better-monadic-for" % "0.3.1"),
// disable .jar publishing
Compile / packageBin / publishArtifact := false,
// create an Artifact for publishing the .war file
Compile / packageWar / artifact := {
val prev: Artifact = (Compile / packageWar / artifact).value
prev.withType("war").withExtension("war")
},
// add the .war file to what gets published
addArtifact(Compile / packageWar / artifact, packageWar),
)
and the compile has complained:
/home/developer/scala/user-svc/build.sbt:27: error: not found: value packageWar
Compile / packageWar / artifact := {
^
/home/developer/scala/user-svc/build.sbt:28: error: not found: value packageWar
val prev: Artifact = (Compile / packageWar / artifact).value
^
/home/developer/scala/user-svc/build.sbt:33: error: not found: value packageWar
addArtifact(Compile / packageWar / artifact, packageWar),
^
/home/developer/scala/user-svc/build.sbt:33: error: not found: value packageWar
addArtifact(Compile / packageWar / artifact, packageWar),
What am I doing wrong?
There is a bug in documentation - see https://github.com/sbt/sbt/issues/4490
Try using dedicated sbt plugin - xsbt-web-plugin - instead of reading that website. According to current docs you need to add to project/plugins.sbt
addSbtPlugin("com.earldouglas" % "xsbt-web-plugin" % "4.2.0")
then enable plugin in build.sbt e.g. Jetty
enablePlugins(JettyPlugin)
then you could build WAR with package command.

I am wrestling with importing required jar files and deploying them into scala projects after writing build.sbt script. Resolvers deny downloading any scala libraries from neither sonar and maveen 2 resolvers. My scala version is 2.13.0 and sbt is 1.6.1
after compiling sbt builds the program yields errors stated below.

Fix the Scala version in your build.sbt and it should be it.
I created Scalatara application to build a web service. It uses Jetty server and it was included in the build.sbt file when I created the project itself.
But when I try to start the jetty server using the command - jetty:start, it shows me an error message "not a valid key: jetty". Then when I checked the build file, it shows a warning message as "unknown artifact in sbt" for the below dependency.
"org.eclipse.jetty" % "jetty-webapp" % "9.4.6.v20170531" % "container"
I used the latest dependency from the MVN Repository but still, it shows the same error. Is there anything else I have to do here?
How did you create the project? Is there a way you can tell me so I can reproduce it. Will be much easier to figure out. Anyways, you can try to add a resolver first to your build.sbt :
resolvers += "Jetty" at "https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-webapp"
Kindly compare the code of build.sbt file shown below and if anything missing you should update in you build.st file.

I was able to resolve the problem. actually there is no need to build a fat jar because the "spark-submit" tool will have everything in the classpath anyway.
thus the right way to build the jar file is
name := "Test"
version := "1.0"
scalaVersion := "2.11.7"
libraryDependencies ++= Seq(
"org.apache.hadoop" % "hadoop-client" % "2.7.1" % "provided",

"org.apache.avro" % "avro-mapred" % "1.7.7" % "provided"
)
mainClass := Some("com.test.Foo")
1. use the MergeStrategy, see sbt-assembly
2. exclude the duplicated jars, such as:
lazy val hbaseLibSeq = Seq(
("org.apache.hbase" % "hbase" % hbaseVersion).
excludeAll(
ExclusionRule(organization = "org.slf4j"),
ExclusionRule(organization = "org.mortbay.jetty"),
ExclusionRule(organization = "javax.servlet")),
("net.java.dev.jets3t" % "jets3t" % "0.6.1" % "provided").
excludeAll(ExclusionRule(organization = "javax.servlet"))
)
3. use the provided scope
show dependency tree:
➜ cat ~/.sbt/0.13/plugins/plugins.sbt
addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.7.5")
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.11.2")

I'm trying to run a Lift-2.4 web app following this tutorial http://scala-ide.org/docs/tutorials/lift24scalaide20/index.html
The problem is how to run this app (either on jetty, tomcat or other server)?!
I'm trying the command jetty-run, but I've got this error:
> jetty-run
[error] Not a valid command: jetty-run
[error] Expected '/'
[error] Expected ':'
[error] Not a valid key: jetty-run (similar: run)
[error] jetty-run
[error] ^
And when I do container:start, I've also got an error:
> container:start
[error] Not a valid key: start (similar: state, target, start-year)
[error] container:start
[error]
^
My configurations are:
The file "build.sbt" contains:
name := "lift-basic"
organization := "my.company"
version := "0.1-SNAPSHOT"
scalaVersion := "2.9.1"
EclipseKeys.createSrc := EclipseCreateSrc.Default + EclipseCreateSrc.Resource
libraryDependencies ++= {
val liftVersion = "2.4"
Seq(
"net.liftweb" %% "lift-webkit" % liftVersion % "compile",
"net.liftweb" %% "lift-mapper" % liftVersion % "compile",

"org.scala-tools.testing" %% "specs" % "1.6.9" % "test",
"com.h2database" % "h2" % "1.2.147"
)
}
And the file ".sbt/plugins/build.sbt" contains:
//Eclipse Plugin
resolvers += Classpaths.typesafeResolver
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.0.0")
It sounds like you need to install the xsbt-web-plugin plugin for sbt.
Instructions are available here: https://github.com/JamesEarlDouglas/xsbt-web-plugin/wiki
That should provide you with container:start as well as jar packaging.
I've just upgraded to sbt 0.11.1 that doesn't seem to be fetching a
certain dependency. Things worked fine before the upgrade.
I have this dependency:
"org.scalatra" %% "scalatra" % "2.1.0-SNAPSHOT",
And when I compile:

After blowing away not just ~/.ivy2 but ~/.m2 and ~/.sbt as well, everything worked again.
Sometimes ivy cache entries get corrupted - simply remove ~/.ivy2/cache/org.scalatra/scalatra_2.9.1/jars/, and let SBT re-fetch the dependency from the remote repo. If it doesn't work, try to remove an entire cache directory (~/.ivy2/cache).
I have had occasions where Ivy has got confused. I can't tell you why, unfortunately, but I have found that things work fine after deleting the entire ~/.ivy2 directory hierarchy. Clearly you'll have to download all your dependencies again, though :-(
